- Description
- KRT19, a member of the keratin family which exists as a heterotetramer of two type I and two type II keratins, is involved in the organization of myofibers. Together with KRT8, KRT19 helps to link the contractile apparatus to dystrophin at the costameres of striated muscle. KRT18 is expressed in a defined zone of basal keratinocytes in the deep outer root sheath of hair follicles. It is also observed in sweat gland and mammary gland ductal and secretory cells, bile ducts, gastrointestinal tract, bladder urothelium, oral epithelia, esophagus, ectocervical epithelium (at protein level). It is expressed in epidermal basal cells and in nipple epidermis. It is also evident in a subset of vascular wall cells in both the veins and artery of human umbilical cord, and in umbilical cord vascular smooth muscle, as well as in muscle fibers accumulating in the costameres of myoplasm at the sarcolemma in structures that contain dystrophin and spectrin.
